Description
When your old muffler starts blowing exhaust into the cab or making more noise than the engine itself, it’s time for a replacement. A worn-out muffler doesn’t just sound bad—it can let dangerous fumes into your workspace and make those long days in the field even more uncomfortable. This vertical muffler is built to handle the heat and vibration from your diesel engine while keeping things quiet and safe.
What You’re Getting
- Oval body design that fits tight spaces while providing excellent sound dampening
- Vertical mounting saves valuable real estate around the engine compartment
- Heavy-duty construction that stands up to the heat cycles and vibration of hard farm work
- Precise inlet and outlet sizing for proper exhaust flow and backpressure
- Direct replacement that bolts right up to your existing exhaust system
Built for Real Farm Work
This muffler is designed for the D310 and D358 diesel engines found in International Harvester’s workhorse tractors from the 1970s and 80s. These machines were built to handle everything from field work and hay operations to loader duties around the farmstead. Whether you’re running a Hydro 86 or one of the numbered series tractors, this muffler will keep your engine breathing properly while you get the job done.
Made to Last
Farm mufflers take a beating from constant heat cycles, moisture, and road salt in winter. This one’s built with materials that resist corrosion and thermal stress, so it’ll keep doing its job season after season. The oval body design provides more internal volume than round mufflers, which means better sound control and longer life.
Installation Notes
This is a direct bolt-on replacement that uses your existing exhaust pipe connections. Make sure to let the engine cool down completely before starting the job, and check that your exhaust pipes are in good shape while you’re at it. A little anti-seize compound on the threads will make future removal easier if needed.
